44 WATTLES AND WATTLE-BARKS. 



1). Momba, Wilcannia. Height, 30 to 40 feet ; diameter, 12 to 18 inches. 

 Collected August, 1887 ; analysed September, 1888. Not flaky on the out-- 

 side like No. 1, but a harder, bonier bark, more rugged, but obviously a 

 promising bark. Thickness, up to 1 inch. Tannic acid, 13*51 per cent, 

 extract, 33 '1 per cent. 



A sample from the Lachlan River, New South Wales, which has been 

 in the Technological Museum five years, is a good specimen of this bark, 

 being fairly smooth, close, compact, and containing comparatively little 

 fibre. It was analysed May, 1890, and found to contain 15' 1 per cent, of 

 tannicacid, and 3275 per cent, of extract. 



This species is undoubtedly worthy of conservation, and even culture, in 

 the dry interior when it is found, particularly as the barks there are usually 

 so poor in tannic acid. The blacks are aware of the value of this tan-bark, 

 as they use it for tanning wallaby and other skins. 



An interior species, found in all the colonies except Tasmania. Habitat, 

 chiefly on banks of creeks and watercourses. 



17. Acacia linifolia, Willd., B.FL, 371. 



A "SALLY." 

 (See A. prominens.) 



Dr. T. L. Bancroft, of Brisbane, was kind enough to send me bark of this 

 tree from Enoggera, near that city, and furnished the following note : " In 

 gullies this species grows to the height of 20 feet or more, but on dry ground 

 is only a whip-stick ; the same remarks also apply to A. complanata. Both 

 these species grow on the edge of the scrub, and there thrive well." 

 Height, 20 feet ; diameter, 6 inches. [Memo. : The tree never attains this 

 size within 200 or 300 miles of Sydney.] Stripped in May ; analysed in 

 July; and found to contain 11'13 percent, of tannic acid, and 2S'15 percent, 

 of extract. 



The bark analysed was poor, thin, and flaky externally. It is inclined to 

 be fibrous, the thickness is under -|- inch, and altogether it is not a promising 

 bark. 



Found in New South Wales and Queensland, usually in the coast 

 districts. 



18. Acacia prominens, A. Cunn., B.FL, ii, 371. 



Eeduced by Baron yon Mueller to a variety of A. linifolia, Willd. 

 This is called " G-rey " and "Black Wattle" near Sydney, but dealers 

 will not have it, and it hardly pays to cut up and pass with better bark. A
